Suggested are a first processing step of manufacturing an initial concrete boundary stone by placing concrete in a mold and manufacturing a first concrete boundary stone by spraying a cleaner and first silicon carbide to the initial concrete boundary stone, a second processing step of manufacturing a second concrete boundary stone by applying a first penetrating concrete reinforcing agent to the first concrete boundary stone, a third processing step of manufacturing a third concrete boundary stone by spraying second silicon carbide to the second concrete boundary stone, a fourth processing step of manufacturing a fourth concrete boundary stone by spraying third silicon carbide and a second penetrating concrete reinforcing agent to the third concrete boundary stone, and a fifth processing step of manufacturing a final concrete boundary stone by truncating the fourth concrete boundary stone with a polishing device. According to the suggested invention, the processes can make a concrete boundary stone smooth compared to an existing concrete boundary stone and variously categorize boundary stones by coloring the concrete boundary stone by using various colors of pebbles or adding paints for the initial concrete boundary stone. For example, if the concrete boundary stone is colored, an effect of clearly dividing areas is obtained and the areas are quickly checked by distinguishing boundaries with colors. Moreover, a permanent gloss effect can be obtained, strength is improved, dustproof and waterproof properties are excellent, and impact resistance and durability are excellent. Thus, a crack of the concrete boundary stone can be prevented. |
